What tools do folks use for protocol decoding?
(1/3) > >>
Lathe26:
I'm curious what tools folks use for offline protocol decoding after they have captured data from an oscilloscope or a logic analyzer?

For example, I have a Rigol oscilloscope that can save capture data to a file.  While it natively supports a handful of protocol decodings, there are many it doesn't and does not appear to allow end-users to write their own.  I am looking at loading the data into Sigrok/Pulseview since it has many protocol decoders, they are written in Python, and it's open source.  However, there might be alternative tools out there.

The best I know is sigrok.  Sometimes wireshark, too.

I remember from some years ago sigrok/Pulseview was starting to support Rigol oscilloscopes.  Should be able to work using oscilloscope's SCPI, so without exporting to a file, but I didn't check how good the support is in practice.

I don't do a lot of protocol decoding, but when I do.. I have a totally official, definitely not Chinese knockoff I bought for $12 from eBay, Saleae Logic.  Their software is pretty good.

I just use my Saleae (legit) to save the capture and export the decoded data into excel.

I believe you can write your own decoders for Saleae LA's as plugins, but its not something i've ever looked into, so i'm not sure.

Looks like a sigrok/pulseview fork.  :-//
